Abstract

A modular exhaust manifold 1 for a motor vehicle, with multiple adjoining manifold pipe modules, having: at least one engine flange, via which an inlet connection pipe of the manifold pipe modules can be connected to a cylinder head of the motor vehicle; at least one manifold pipe module, configured as a collector pipe module and having a contact flange, via which the exhaust manifold can be connected to an exhaust system of the motor vehicle, the respective manifold pipe modules having an overlap contour of a length a that permits the telescoping of two manifold pipe modules to an insertion depth t for coupling purposes, at least two manifold pipe modules being identical in shape, and a variation of the insertion depth t of at least 5 mm to 30 mm or 10 mm or 15 mm or 20 mm or 25 mm being obtained by the formation of length a of the overlap contour. A method for producing a manifold formed from multiple adjoining manifold pipe modules.
